What is the FAA Part 107 License?

A Remote Pilot Certificate (Part 107 license) is mandatory if you plan on flying your drone for all non-recreational purposes. Part 107 rules are applicable for all drones weighing less than 55 pounds.   If you are only flying for “recreation and/or hobby purposes” you do not need a Part 107 license.  You should still take and pass the FAA Trust Test.
